Barr & Stroud 'Sierra' 10x50 Phase Coated FMC WP Binoculars

OK you want the power of the 10x42 model and the light-gathering ability of the 8x42 well you will find that, almost, in the Sierra 10x50 binocular. But as ever there is a trade off and this time it's extra size and weight. The extra 10mm diameter of the object lens results in a lot more glass being used and larger lens barrels to accommodate the lenses. If lightness and portability are high on your requirement list then I would look at either the 32mm or 42mm Sierras, but if you just want super bright powerful binoculars, that don't need you to re-mortgage your house, look no further!

The Sierra range from Barr & Stroud features rugged construction combined with brilliant optics. They are waterproof to a depth 1.5m of water for three minutes, with plenty of time to retrieve them if you have dropped them in a stream or puddle. This requires a high degree of mechanical quality in the construction of the binocular which is evident as soon as you pick the binocular up or use the super smooth focus control wheel. We don't expect that you will make a habit of dropping the binoculars into deep water but we do expect that you will want to use them in any weather the planet can throw at you, so you can feel assured that the Barr & Stroud's Sierra's can take it, again and again. This ability is further enhanced by the binoculars rubber armoured body which protects it from shocks and knocks.

The binoculars are filled with nitrogen gas which keeps water out and also stops the optics suffering from internal fogging in adverse weather conditions, this binocular is truly weatherproof.

Fully Multi Coated optics are standard features of the Barr & Stroud Sierra range as are BaK-4 phase coated prisms. This degree of sophistication ensures that as much light as possible is transmitted through the optics which results in super bright contrast-rich images of high colour fidelity for the user even in low light conditions where less expensive optics and coatings result in a dramatic loss of performance.

For the comfort of the user the binoculars are supplied with metal twist-up eyecups that are rubber coated which make them equally practical for people to use with or without spectacles. The rapid focus mechanism takes the user from close focus to infinity in less than one turn of the focus control knob, which ensures that you can follow the action however fast it is happening.

The Sierra 10x50 is supplied with a carrying case, rain guards, tethered lens caps, straps, and lens cleaning cloth.
